Investigations of chemical reactions between single levitated magnesium chloride microdroplets with SO2 and NOx by means of Raman spectroscopy and elastic light scattering

Jeanette Musick  and  Jürgen Popp  

Abstract

The combination of Raman spectroscopy with an electrodynamic levitation technique enables insitu and non-invasive investigations of chemical reactions in single microparticles without any disturbing substrate or wall effects. Time-dependent Raman spectra during the condensation of a magnesium chloride microparticle (a model substance of sea-salt particles) with water vapour are reported. The condensation of a MgCl2·6H2O microparticle is also investigated by means of elastic light scattering data. Additionally, the solvation of SO2 and NOx in a MgCl2·6H2O microdroplet is studied by Raman spectroscopy. The uptake of these gases is also determined from elastic light scattering data.
